Note
: The I
2
C read data protocol section of this figure implies that the
peripheral addressing phase has already occurred. The I
2
C Interface will
remember where it left off such that new reads to the same device do not
require the peripheral addressing phase; however, an initial read of an I
2
C
device will require a peripheral addressing phase.
